In this week's edition of Sporting News' Huddle Up! Podcast, co-host Vinnie Iyer welcomes special guest George Winkler of SN's Fantasy Source Football to break down the core questions that should be on the mind of every fantasy owner going into the second half of the 2012 season:

Quarterbacks

Will we see fewer mistakes from Tony Romo in Dallas?

Winkler: The Cowboys’ big question is with that offensive line. It was a problem coming into the season, and they really didn’t it address it well in the offseason. That’s where the mistakes are coming from—Romo is feeling a ton of pressure.

Can Peyton Manning keep up his great play in Denver?

Winkler: I liken him to a crafty pitcher who’s lost his fastball, but he can still find his receivers open with short passes, using his guile and his know-how to get things done. He’s got a streak of 300-yard games going and can keep it going this week (at Cincinnati).

Wide receivers

Will Larry Fitzgerald get help from his quarterbacks in Arizona?

Winkler: Touchdowns can still save his season. If they would stop targeting Andre Roberts for those touchdowns and go to Fitzgerald, he’s awesome on those jump balls and fade patterns. We’ve been saying it for years—since Kurt Warner left, he hasn’t had a quarterback. He’s been able to overcome it because he’s such a talented force, but it’s getting tougher and tougher this year because the offensive line is bad and not allowing him to work down the field.

Will Andre Johnson start producing like a WR1 in Houston?

Winkler: Even though he’s slipping down the ranks of the WR1, going the opposite direction of guys like Demaryius Thomas, he’ll rekindle some of the fire in the Buffalo game on Sunday.

Are there enough footballs to go around in Atlanta?

Winkler: That’s the only problem with the Falcons. It’s the problem you’ve had with the Patriots or Packers. In the first quarter of last week’s game, Matt Ryan had already spread the ball around to seven receivers. It’s great he’s working the offense like that from a real-life perspective, because it’s hard to game-plan for and shut down. From a fantasy perspective, you’ve got to throw your hands up, roll your Falcons out there and hope that they come through that week.

Can we trust anybody in the Jets’ passing game?

Winkler: Opposing defenses think the guy is Jeremy Kerley because they have been targeting him with their coverage. He still has a lot of targets, whereas Stephen Hill will fade in and out. Kerley is the safest bet from this group. Clyde Gates, who had 11 targets last week, had 12 all of last season, so you can see that might be a fluke.

Iyer: I think it’s appropriate they have receivers whose names remind you of the Three Stooges and the Pac-Man ghosts because that’s the kind of offense they have with Mark Sanchez—I’m not trusting him at all.

Running backs

Will Trent Richardson become a stud in Cleveland?

Winkler: There are three or four running backs that can carry you to a fantasy title down the stretch, and Richardson is in that mix with Arian Foster, Ray Rice and LeSean McCoy.

Can we trust Steven Ridley in New England?

Winkler: It’s no secret fantasy owners hate Bill Belichick because he messes with his running backs too much for our taste. Ridley, though, has been very productive with the few carries that he’s gotten. He’s got only 54 percent of his team’s carries, low for a No. 1 back. It’s silly to say he’ll be an RB1 moving forward because he’s going to have to be very efficient like he was in the first half.

Is Tampa Bay’s Doug Martin the next Ray Rice?

Winkler: I don’t want to disrespect Ray Rice because he’s been doing it for much longer, but Martin, he certainly has the makeup—he can catch balls out of the backfield, he can run inside and outside. The full thing was on display last week in Minnesota and he has a coach, Greg Schiano, who likes to use one guy, and that’s really rare in the NFL these days.
